[Rd] Getting 'LinkingTo' to find the right library

[Prof Brian Ripley]

Where did you get the idea that R CMD INSTALL is reading .Rprofile?
(AFAIR it does so only to find the installation library, as R CMD 
INSTALL --help says it will.)

You need to set R_LIBS in the environment to get the library path you 
want.  This is not specific to 'LinkingTo'.
